If you want to make changes to an existing trigger, you could use the "ALTER TRIGGER" statements to refine the trigger again. The tutorial exercise below shows you how to modify the trigger defined in a previous tutorial:

USE FyiCenterData;
GO

ALTER TRIGGER dml_message ON fyi_users
AFTER INSERT, UPDATE, DELETE 
AS
  PRINT 'Time: '+CONVERT(VARCHAR(12),GETDATE());
  PRINT 'Records are inserted, updated,'
    + ' or deleted in fyi_users';
GO

UPDATE fyi_users SET email='john@fyicenter' WHERE id = 1;
GO
Time: Jul  1 2007 
Records are inserted, updated, or deleted in fyi_users

An extra printing statement is added the trigger.
